.To all whom it may concern:

Be it known that I, SAMUEL T. Bonn, a citizen of the United States, anda resident of the city and county of Philadelphia, State ofPennsylvania, have invented certain new and useful Improvements inElect-ric Sprinkling- Cars, of which the following is a specification.

The object of my invention is to provide a car of this class which willforce water through the nozzles or allow it to flow by gravity and alsoto provide means for filling the tank when water is supplied witlioutpressure. This object is accomplished by means of my invention, oneembodiment of which is herein described.

For a more particular descri tion of my invention, reference is to beha( to the accompanying drawings, forming a part hereof, in which;

Figure 1 is a view showing a tank and pump and pipe connections betweenthem, as well as portions of the car structure. Fig. 2 is a similar viewshowing the valves opened and closed for a different connection,unnecessary 'parts being omitted. Figs. 3 and 4 are sectional viewsshowing the relief-valve, Fig. 4 being taken on the line 4 4 of Fig. 3looking in the direction of the arrows. Fig. 5 is a plan view oftheparts shown in Fig. 1, the tank being omitted. Fig. 6 is a sideelevation of the parts shown in Fig. 5.

vThroughout the various4 lviews of the drawings, similar referencecharacters designate similar parts.

` The tank 1 is supported on any suitable car-frame 2in the customarymanner, as by the bolsters 3, resting on the floor 4. -This tank 1 isconnected to a vertical pipe 5, which is connectedto a horizontal ip'e6with a valve 7, both located above the floor 4, and a secondhorizontally-disposedV ipe 8, connected at one end to a 4centrifuga ump'9 and at its other to a vertical pipe 10, t at 1s connected with thenozzle supply-pipe 11, which is preferably placed abovev the floorlevel.The nozzle supply-pipe -11 is con. nected by a T 12 to the cross-lpipe13, which is united by elbows 14 to the ongitudinallyextendingnozzle-pipes 15. The nozzles at the ends of these pipes may be of anysuitable The pipe 5 is provided with a relief-valveV 1 6, which isconveniently located between the pipes 6 and 8. This relief-valve isshown somewhat in detail in Figs. 3 and 4. The casing 17 is preferablygiven the Shape indicated and is provided with a spindle 18 near itslower end. This spindle 18 is journaled in the casing 17 and ha's itsouter end protrude through a stulling-box 19, and a handle 2() is fixedto this projecting part. AA cam 21 is fixed to this spindle 18 and actsto raise a valve 22 from its seat 23 against the action of a spring24,which surrounds a rod 25, that is riveted at its upper end to acrossing 26 in the casing 17 The valve 22 is also provided withdiametrically opposite and parallel guides 27, which run verticallybetween ixed guides 28. The movement of this valve 22 is limited in avertical direction b the rod 25 and seat 23. The-casing 17 issu icientlyenlarged at 29 to permit the water to low freely by the valve 22 when itis raised from its seat either by the cam 21 or the pressure of thewater under the valve 22, which may be sufiicient to overcome theresistance ofl'ered by the spring 24, as will more fully appear below'.

The outflow-opening of the pump 9 is connected with the pipe 8 in anysuitable manner. The inflow-opening is connected similarly to a pipe 30,which is united to a T 31, which is fixed to a valve 32 and horizontalpipe 33, which is adapted to be connected with any suitable source ofwater-supply. The third opening of the T 31 is connected by a verticalpipe 34 and elbow 35 to the short pipe 35a to the valve 7.

The pump 9 is connected b a shaft 36 to a motor 37. The pump 9 an motor37 may be su ported in any suitable way as' may be found) mostconvenient. In Fig. 6 they are shown under the car-body. The preciseform of support from the car-body is not shown, as it is obvious thatany well-known sort of suspended platform may beremployed.

From the foregoing 'the operation of my `improved sprinkler will bereadily understood. In Fig.^1 the arrows indicate the direction taken bythe water when forced into the tank .1. This waterenters through thepipe 33, valve 32, T 31, pipe 30, pump 9, pi e 8, through the valve16,whichisopened byt e cam 21 and pipe 5 into the tank 1, the va IOC andnozzles being closed. When the tank i' is filled, the valves 32'and 16are closed and leave its seat.

it is not necessary to stop the motor at anyy time While the car is inuse, o r if the effect of the pump is not desired the motor may bestopped and'water allowed to How through it as a pipe, or both of thesemethods of use may be alternately employed.

In the foregoing has been described one embodyment of my invention. Itis obvious that many others may be employed which ,utilize its essentialcharacteristics, so that I do not regard it as limited to the recisedisclosure hereinmade, but as broa enough to cover all structures thatcome within the scope of the annexed claim.

What I claim is- In a device of the class described, a combination of atank and induction-pipe leading downwardly therefrom, a springrelief-valve in said pipe, and manually-operated means in said valve foropening the same against the action of said spring, a pump connectingwith said pipe and also with a nozzle-pipe and branch pipe leadingaround said pump from the induction side of. the'pump to said tankinduction-pipe, and a valve .in said branch pipe and also means forconnecting 'said branch pipe with a source of Water-su ply, whereby saidpump while continuous yv running in one direction may be caused t fierceliquid into said tank, or to withdraw liquid therefrom and supply it tothe nozzlepipe, or to simply circulate the liquid when the nozzles areclosed, whereby all undue stresses are removed from the nozzles. i
